There apparently have been a couple of actual cases of the lock self-engaging, and countless unrelated operational problems blamed on the lock by those who don't know how revolvers work, and can't strip their guns or diagnose malfunctions. Guys who refuse to buy a lock gun because it might malfunction are, I think, being a little disingenuous. The lock is easily disabled, so that really shouldn't be an issue. Fearing liability concerns is silly. All of my revolvers have a mix of aftermarket springs, firing pins, sights, grips and action jobs. Those modifications don't worry me or most anybody else. Why should deactivating a storage lock be a factor? I don't like the lock on aesthetic grounds, period. I currently have three revolvers with the lock, alloy Airlites that aren't produced without it. I wouldn't consider buying a steel gun with the lock, but not because I'm afraid it might self-engage. I just don't like the things.
